The Gravity Single Relay Moduleblocks the number of electronic modules. It can be used in interactive projects.  It can also be used to control the lighting, electrical and other equipments. The modular design makes it easy to expand with the Arduino board (not included). The Relay output state by a light-emitting diode. It can be controlled through the digital IO port, such as solenoid valves, lamps, motors and other high current or high voltage devices.

Customer Reviews

Based on 3 reviews

Worked great with DFRobot Mega IO Expansion Shield. Connected up to 6 relays and worked with solely usb power to the Mega.

Very Useful . Five stars.

I like this relay because it can be used with 5V and 3.3V Arduino and similar microcontrollers. There is also a NC contact in addition to the normally open so the relay contacts act like a SPDT switch. The contacts can handle 10A. High signal from the microprocessor turns on the relay (green wire). Red wire is for + power, black wire for - power. Here is what DF Robot says about it: It is specially designed for low-voltage devices and works well under 3.3V power supplies, just like the Raspberry Pi relay board. In addition, the module has a wide range of power inputs. In our tests, once it reaches 2.8~5.5V, it can also support 1.8V devices. DFRobot’s Digital Relay Module uses a high quality 3V relay. It can handle up to 10A current and mechanical parts are guaranteed up to 100 million uses. An on-board indicator LED demonstrates the relay’s state. Terminals include normally open (NO) and normally closed (NC). The module uses a Gravity-3 pin interface, which requires no soldering for convenient plug and play usage. Introducing the Gravity Digital Relay Module – the latest addition to DFRobot’s Gravity series! This module is a little different to the other relays in our store - not only is it compatible with 5V Arduino boards, but also with Raspberry Pi, BBB (BeagleBoard Black), mbed, Intel Joule, Arduino 101 and other 3.3V devices. Operating Voltage: 2.8V ~ 5.5V Input Signal: High Level (≥2.8V); Low Level (≤0.5V) Max Switching Current: 10A

Practical and easy to use

It's a good product for any application you may have. This relay is easy to wire and understand, so anyone can switch between two different voltage supply.
